I didn't even realize this was Kaguya from Kaguya-sama, Love is War, until after I finished reading and was checking the tags more. Not really sure why the artist even used that character, she didn't mention anything about her old life, or friends, or anything.
Okay, didn't realize that this was a continuation. Still, it would be nice to maybe get an update on what's happening with Miyuki or Chika.
